<tt><font size=2>I should clarify my comment about invoking Heat to do
the orchestration. I think we have a choice between designing a 1-stage
API vs a 2-stage API. The 2-stage API goes like this: first the client
defines the top-level group and everything inside it, then the client makes
more calls to create the resources (with reference to the groups and policies).
In the 2-stage API, there is no need to use Heat for orchestration
--- the client can orchestrate in any way it wants (BTW, we should eventually
get around to talking about what happens if the client is the heat engine).
In the 1-stage API, the client just makes one call to define the
top-level group and everything inside it; the implementation takes care
of all the rest; in this style of API, I think it would be natural for
the implementation to call Heat to do the orchestration.</font></tt>
